Derivative F-Terms from Heterotic M-Theory Five-brane Instantons
Evgeny I. Buchbinder
TL;DR
This paper investigates how heterotic M-theory five-brane instantons induce non-perturbative derivative F-terms in the effective theory, expanding understanding of their role beyond superpotential contributions.
Contribution
It demonstrates that five-brane instantons contribute to derivative F-terms, not just superpotentials, providing new insights into non-perturbative effects in heterotic M-theory.
Findings
Five-brane instantons contribute to derivative F-terms.
These effects are distinct from superpotential contributions.
The results expand the understanding of non-perturbative effects in string theory.
Abstract
We study non-perturbative effects due to a heterotic M-theory five-brane wrapped on Calabi-Yau threefold. We show that such instantons contribute to derivative F-terms described recently by Beasley and Witten rather than to the superpotential.
